A father with hepatitis B has a chance of infecting his child with the hepatitis B virus after the child is born through later life contact. Hepatitis B virus is transmitted through blood, sexual contact, mother-to-child, and close personal contact. The most common ways of transmission between the child and the father are blood transmission and close contact transmission. 1. Blood transmission: If the father is infected with hepatitis B virus, and if the child has a wound or mucous membrane defect and comes into contact with the father’s blood, saliva, etc., the body fluids contaminate the wound and there will be a chance of infection. And then the father will give the child blood transfusion will also increase the chance of infection. 2. Close contact transmission: if you use towels, cups, chopsticks, bowls and so on with your father for a long time in daily life, it will also increase the chance of hepatitis B virus infection. Parents need to check their children’s Hepatitis B 5 on a regular basis, and get a booster shot of Hepatitis B vaccine if necessary. Children should avoid close contact with their parents if they have hepatitis B.
